How to Store Sesame Oil: Toasted and Untoasted
Kikkoman USA permits opened toasted sesame oil in a cool, dark cupboard. Kadoya’s Japanese FAQ gives an approximate 1–2 months after opening, depending on storage, and recommends upright, tightly capped storage in a dark place at 20°C±5, away from heat and moisture. La Tourangelle recommends use within six months of opening, subject to the can’s earlier printed expiration date; the inspected sources do not establish a storage location for its toasted sesame oil. Keep these maker instructions separate.
Quick answer

Purchase explicit; not unopened or additive.

Kadoya’s Japanese FAQ recommends finishing opened oil in about 1–2 months, depending on storage. Keep it upright and tightly capped, dark at 20°C±5, away from accumulated heat/moisture. The maker discourages chilling/freezing because of solidification and condensation concerns.

No new elapsed clock.
Why guidance varies
Toasted and untoasted products and regional maker directions differ. La Tourangelle’s inspected guidance supplies an opening recommendation for toasted sesame oil without establishing its storage location.

Frequently asked questions
Should every toasted sesame oil go in the fridge?
No blanket requirement is established. Kikkoman USA permits a cool/dark cupboard, and Kadoya’s Japanese guidance discourages cold storage. La Tourangelle’s inspected sources do not supply a location for its toasted sesame oil.
Can I use Kikkoman’s sauce period for sesame oil?
No. Its sauce answer names sauces; the separate sesame-oil answer specifies storage location without an elapsed oil period.
